The invention relates to a sequentially controlled water mixer comprising a valve housing (1) with a cold water inlet connection (2) and a hot water inlet connection (3), and a common outlet (4), said casing defining a mixing chamber (5) between the inlets and outlet with a regulating chamber (6) located on the inlet side for housing an adjustable regulating switching valve (7) of substantially rotationally-symmetrical shape and with regulating apertures (8,9), said valve being adjustable to seal-off the inlet connections (2,3), or to control flow through the connections via said apertures (8,9). According to the invention the said inlet connections define recessed holes of larger dimension than respective hot and cold water pipes to be used therewith, and each hole accommodates a compression spring (27) and a seal (28) loaded by the spring to rest in contact with said switching valve (7) via a sealing surface which follows the contour of said switching valve. This sealing surface has a through hole (31) for the flow of water, and is provided peripherally with holes or the like (33) for retaining a lubricant inserted therein. Furthermore, the mixer has at least one operating knob (13) which can be rotationally set relative to the switching valve (7), and a connecting device (34) into or out of which the connections (2,3) in the form of short lengths of pipe, can be inserted, or withdrawn, seals being provided for sealing the inlet connections with the connecting device. |
